摘要
本文给出了数字波束技术中和差波束自适应形成零点的算法,提出了同时得到和差波束自适应零点的一种设想。讨论了各路幅相误差对方向图副瓣及自适应零点的影响,提出了消除幅相误差影响的办法。指出了加权和LMS算法的不可互换性。
This paper deals with the algorithms for forming adaptive nulls of the sum and difference patterns in digital beamforming,and gives an outline of the approach to getting the sum and difference simultaneously.The effects of amplitude and phase errors in the intercoupling and receiving channels on the sidelobe and the adaptive nulling are discussed.A way that eliminates the effects of amplitude and phase errors is presented.It is proved that the weighting and the LMS algorithm can not be interchanged.
